Gas hobs need a Gas Safe engineer
Installing or moving a gas hob is gas work, same as a boiler, and legally needs a Gas Safe registered engineer, not just a kitchen fitter or general plumber. If you're switching from electric to gas (or vice versa) as part of a refit, this needs coordinating separately from the general fitting work.
Cabinet handles and hardware, a small but real cost
Handles, hinges and drawer runners are a small line item individually but add up across a full kitchen, and soft-close mechanisms cost more than standard hinges — worth clarifying what's included as standard in a quote versus what's an upgrade, since this varies between fitters.
KBSA and TrustMark, what they actually mean
The KBSA (Kitchen Bathroom Bedroom Specialists Association) is the main UK trade body for the sector, though membership is limited to a few hundred companies nationally, so not every kitchen fitter will hold it. TrustMark is a broader government-endorsed scheme covering many trades — worth asking which, if either, your fitter holds rather than assuming either is standard.
Understanding the labour vs materials split
Units, worktop and appliances are often the largest share of a kitchen's total cost, but fitting labour, old kitchen removal, and making good around new services add up too. A cheap quote is worth checking against the same unit/worktop spec as competing quotes, not just lower labour.
Kitchen plumbing and appliance connections
A new sink, dishwasher or washing machine needs its own isolation valve and a proper waste connection — moving the sink position, in particular, often means new pipework rather than just reconnecting to the old point. Check whether your fitter handles this directly or brings in a plumber.
Kitchens as part of a wider extension
A kitchen fitted as part of a house extension needs closer coordination between the builder and kitchen fitter on timing — services (electrics, plumbing, ventilation ducting) need to be roughed in during the build phase, before the kitchen fitter's own first-fix stage begins.
Common kitchen fitting jobs
Kitchen fitters handle everything from a single worktop or cupboard door replacement to a full gut-and-refit: removing old units, fitting new cabinetry, worktops, and coordinating the plumbing and electrical work a kitchen needs (sink, dishwasher, oven, extractor). Many fitters manage the whole job and bring in a plumber or electrician for specific parts.
Kitchen ventilation and extraction
An extractor hood vented to the outside removes cooking odours and moisture more effectively than a recirculating (filter-only) hood, but needs ducting planned into the layout — easier to arrange during a full refit than retrofit afterwards. Building Regulations require adequate ventilation in kitchens generally.
